Shrub rose plant named `Ausmol`

ABSTRACT

A shrub rose having repeat flowering with rich yellow old fashioned shaped flowers.

The present invention relates to a new and distinct variety of roseplant of the shrub class which was originated by me by crossing thevariety Graham Thomas with an unnamed seedling.

The primary objective of this breeding was to produce a new rose varietyhaving yellow repeat-flowering shrub with old-fashioned-shaped flowers.The objective was substantially achieved, along with other desirableimprovements, as evidenced by the following unique combination ofcharacteristics that are outstanding in the new variety and thatdistinguish it from its parents, as well as from all other varieties ofwhich I am aware:

1. Rich yellow flowers.

2. Old-fashioned shape of flower.

3. Good repeat flowering.

Asexual reproduction of this new variety by budding, as performed atAlbrighton, Wolverhampton, England shows that the foregoing and allother characteristics and distinctions come true to form and areestablished and transmitted through succeeding propagations.

The accompnaying illustration shows typical specimens of the vegetativegrowth and flowers of this new variety in different stages ofdevelopment, depicted in color as nearly true as it is reasonablypossible to make the same in a color illustration of this character.

The following is a detailed description of my new rose cultivar withcolor descriptions using terminology in accordance with The RoyalHorticultural Society (London) Colour Chart, except where ordinarydictionary significance of color is indicated.
